How to Use Power BI Python



What Is Python Scripting

Python is a high-level, interpreted programming language that is widely used for web development, scientific computing, data analysis, artificial intelligence, and many other tasks. It is known for its simple and easy-to-read syntax, making it a popular choice for beginners and experienced developers alike. Python also has a large and active community which creates and maintains a wide variety of libraries and modules that can be easily imported and used in Python programs. Some of the key features of Python include:

  • Dynamically typed

  • Supports multiple programming paradigms (procedural, object-oriented, functional)

  • Has a large standard library

  • Has an interactive interpreter

  • Can be used for a wide range of tasks, such as web development, data science, and artificial intelligence

Power BI Desktop And Python Integration

To enable Python scripting on your Power BI Desktop. To do this, just go to File, then click on Options and Settings. Under Options, you'll find Python Scripting. Always make sure that you set the right installation path for Python. If Python script options page appears, supply or edit your local Python installation path under Detected Python home directories.


Here is a Vido Showing You How To Do This:


Ways To Use Python In Power Integration


Using the "Python Script"

Using the "Python Script" data connector: This allows you to connect to a data source using a Python script and then use that data in your Power BI report.


Using the "Python Visual"

sing the "Python Visual" in Power BI: This allows you to create custom visualizations in Python and then use them in your Power BI report.


Embedding a Python script in Power Query:

Embedding a Python script in Power Query: Power Query is a data connection tool that is integrated into Power BI. It allows you to perform data transformations and cleaning using a visual interface or M language. By using the Python script in Power Query you can perform more complex data manipulation.


Automating Power BI tasks with Python:

Automating Power BI tasks with Python: You can use Python libraries such as powerbi-python to automate tasks such as creating reports, managing datasets, and more.

By using Python in Power BI you can leverage the powerful data manipulation and visualization capabilities of Python with the interactive reporting and sharing capabilities of Power BI.

It's important to note that you need to have Python installed on your computer and have the necessary libraries installed to be able to use Python in Power BI.


Benefits Of Python In Power BI:

Data Preparation:

Python has a wide variety of libraries and tools for data manipulation and cleaning, which can be used to prepare data for analysis in Power BI.


Advanced Analytics:

Python has a large number of libraries for advanced analytics, such as machine learning, natural language processing, and computer vision, which can be used to add additional functionality to Power BI.


Automation:

Python can be used to automate the process of data extraction, transformation, and loading (ETL) into Power BI, making it easier to maintain and update the data pipeline.

Integration:

Power BI and Python can be integrated to allow for the use of Python's libraries and functionality within Power BI and to easily visualize and share results.

Scalability:

Python is a versatile and powerful language that can handle large amounts of data, making it a great choice for data analysis and visualization tasks in Power BI.


Community:

Python has a large, active and supportive community which allows you to leverage the work of others and to find solutions to problems you encounter quickly.


Importing Data With Python

To import data using a Python script in Power BI, you can use the Power BI Python Data Connector. The connector allows you to connect to external data sources using Python, and then import the data into Power BI. Here are the general steps to do this:

Install the Power BI Python Data Connector by going to the "File" menu in Power BI Desktop, selecting "Options and settings" and then "Python scripting".

Once the connector is installed, you can use Python code to connect to a data source and retrieve data. For example, you can use the pandas library to read data from a CSV file or a SQL database.


After you've retrieved the data, you can use the powerbi library to import the data into Power BI. The powerbi library provides a push_data method that you can use to send the data to Power BI.


Once the data is imported into Power BI, you can use it to create visualizations, reports, and dashboards.


You can use the Power BI Python SDK to automate Power BI tasks using Python. You can use the SDK to create reports and dashboards, import data, and perform other tasks programmatically.


Please note that the above steps are just an overview, and you will need to have knowledge of Python, Pandas and Power BI SDK to perform the task. Also, you need to have a valid credentials to connect to the external data sources and make sure that the data source is accessible from the machine where you are running the script.


How To Install Python and Python Scripting On Your PC

There are several ways to install Python on your PC, depending on your operating system and desired setup. Here are a few common methods:


Downloading an installer from the official Python website:

Downloading an installer from the official Python website: Go to the official Python o avoid these issues, use the official Python distribution from https://www.python.org and download the appropriate installer for your operating system. Once the download is complete, run the installer and follow the prompts to install Python.


Using the package manager for your operating system:

Using the package manager for your operating system: On Windows, you can use the Chocolatey package manager to install Python. On MacOS and Linux, you can use Homebrew or apt-get, respectively.


Using the Anaconda distribution:

Using the Anaconda distribution: Anaconda is a distribution of Python that includes many popular libraries for data science and machine learning. It also includes a package manager called aconda that makes it easy to install and manage packages.

Once Python is installed, you can check the version of Python by running python --version in the command line.


It's important to note that when you install python it comes with the Python Standard Library, which includes a large number of modules that provide useful functionality such as file I/O, string manipulation, and more. However, many additional libraries and modules are available that are not included in the standard library, so you may need to install them separately.


Can Python Be Used With Power BI Gateway ?

Yes, Python can be used with Power BI Gateway in order to fetch and manipulate data from different sources and then connect it to Power BI.

Power BI Gateway is a service that allows you to refresh your Power BI data when it's coming from sources that are not supported by Power BI or when the data is located on-premises.


You can use Python to fetch data from different sources, clean and transform it and then use the Power BI Gateway to connect to it.

One way to do this is to write a Python script that connects to the data source, performs the necessary data manipulation and then saves the data in a format that Power BI can connect to (such as a CSV or Excel file).


Then you can set up a scheduled refresh for the dataset in Power BI, which will automatically update the data in Power BI when the data changes in the source.

Another way is to use Python to create an API that serves the data and then connect Power BI to this API using the Web connector.


It's important to note that for the above methods to work, you need to have the Power BI Gateway installed and configured on your machine, and also have Python installed and the necessary libraries to perform the data manipulation.
